Hi Andrew
Thanks for replying. the yield was actually there: test function is:
def await(seconds):
d = defer.Deferred()
reactor.callLater(seconds, d.callback, True)
return d
@defer.inlineCallbacks
def test():
thing = yield await(2)
print "hey"
Do you have any idea how to work around? Thanks
Regards
gelin yan
